Estou agarrado nesse desafio, ele funciona com o ForEach que eu comentei:

<jsp:useBean id="dao" class="br.com.caelum.agenda.dao.ContatoDao" />
		<table border="1">
			<c:forEach var="contato" items="${dao.lista}" varStatus="id">
				<tr bgcolor="#${id.count % 2 == 0 ? 'aaee88':'ffffff' }">
					<th>Nome:</th>
					<td>${contato.nome}</td>
					<th>Email:</th>
					<td>
						<c:choose>
							<c:when test="${not empty contato.email}">
								<a href="mailto:${contato.email }">${contato.email}</a>
							</c:when>
							<c:otherwise>
								E-mail não informado
							</c:otherwise>
						</c:choose>
					</td>
					<th>Endereço:</th>
					<td>${contato.endereco}</td>
					<th>Data de Nascimento:</th>
					<td><fmt:formatDate value="${contato.dataNascimento.time}" 
					pattern="dd/MM/yyyy" /></td>
				</tr>
			</c:forEach>
		</table>

no arquivo lista-contatos.jsp mas usando Display Tag ele não funciona.

<jsp:useBean id="dao" class="br.com.caelum.agenda.dao.ContatoDao" />
	<% 
		request.setAttribute("tabela", dao.getLista()); 
	%>
	<display:table name="tabela">
		<display:column title="nome" property="nome" />
		<display:column title="email" property="email" />
		<display:column title ="endereco" property="endereco" />
	</display:table>
